MAHLON E. LAYNE, 01E HOUSTON, TEXAS MOVABLE POWER UNIT.

Application filed September 5, 1922. Serial No. 586,348.

To all whom it may concern:

Be it known that I, MAHLON E. LAYNE, a citizen of the United States,residing at Houston, in the county of Harris and State 5 of Texas, haveinvented a new and useful Movable Power Unit, of which the following isa specification. V

This invention relates to a movable power unit and is particularlydirected to a driving motor laterally movable to or from a position ofoperative connection with a driven mechanism.

An object of the invention is to provide a power unit adapted to beoperatively connected with a driven mechanism and associated with meansfor elevating said unit and laterally translating it away from saidmechanism.

Another object is to provide lateral tracks upon which wheeled truckstravel, and to provide means between the trucks and the power unit,operative in one instance to elevate and support the power unit forlateral translation, and in another instance to lower 26 the powerunitto position of use free from support by the trucks.

A further'object is to provide a vertical driving motor adapted to bedirectly connected to the driven shaft of a centrifugal 30 deep wellpump and having associated wheeled trucks adapted to travel laterallyupon track members, and to provide jackscrews or lifting means betweenthe motor and said trucks whereby the motor and its support or frame maybe elevated and supported upon the trucks for lateral translation awayfrom the well to aii'ord access to the well mechanism, or to be loweredto position of use free from support bythe trucks.

Another object is to provide a pump-head structure including trackmembers upon which a motor supporting and elevating means is adapted totravel in a lateral translation of the motor to and from the pumphead. II

Various other objects and advantages will be more fully apparent fromthe following description of the accompanying drawings which form a partof this disclosure and which illustrate a preferred form of embodimentof the invention.

.members.

Fig. 5 is a detail section on line 5-5 of Fig. 4c.

In the drawings is illustrated a vertical electric motor as the powerunit utilized in this instance to drive a centrifugal deep well pump andadapted to be laterally translated to and from a position of use overthe pump head, but it is to be understood that this is only illustrativeof one of the various embodiments towhich the structure of the presentinvention is susceptible, and that other specific types of motors may beemployed if desirable.

In the specific embodiment shown, 1 designates the well casing in whichis positioned the well tubing 2 leading down into the well to a suitablecentrifugal pump (not shown) and communicating with a well head 3 havinga discharge pipe 4. The pump shaft 5 extends upwardly through the pumphead 3 and carries one member of a separable shaft coupling which isindicated generally by the reference character 6 and which may be of anydesirable or well known type. The as pump head has a table plate 7 uponwhich the power unit rests when in position of use.

This general form of well mechanism is now so well known in the art thatfurther on detailed description thereof would be superfluous.

In the present instance the structure for supporting the pump head 3includes two parallel beams 8 which extend upon opposite o5 sides ofsaid head and Which also serve as track members upon which the powerunit is translated. These beams 8 are preferable channel beams, theirmedial web being secured to the pump head 3 by bolts 9 and 5100 theiropposite ends resting upon and secured to transverse beams 10 embeddedin concrete.

This provides a pump head structure supported by opposed parallel truckmembers and contributes to a simple, cheap and durable means ofsupporting the pump. However, it will be evident that instead of boltingthe tracks to the pump head by the bolts 9, the pump head may restdirectly upon the foundation, leaving the tracks as separate individualmembers.

The power unit in the present embodiment of'the invention, comprises avertical electric motor 11 superposed upon a motor stand 12 which is cutaway as at 15 so that as the motor is translated to position over thepump head 3, the pump shaft 5 and other parts of the pump head may passthrough said side opening 15 to a position within the motor stand.

The means for elevatin and translating the motor, consists of uplicatewheeled trucks, indicated generally by the reference character 16, andadapted to travel along the top surfaces of the beams 8. Each truckconsists of opposed members 17 joined together by an intermediate angleiron 18, and supporting wheels or rollers 19 journaled in the forkedends of the members 17. Guide fingers 20 are secured to the trucks anden gage over the outer top edge of the beams 8 to maintain the trucks inproper alignment u on the tracks. Each member 17 is provlded with arecess 21 and projecting outwardly from the base ring 14 of the motorstand 12 are bosses 22 carrying vertically disposed jack-screws 23, saidjack-screws having a screw threaded engagement in the respective bossesand extending downwardly into the recesses 21 of the trucks so that uponturning the jack-screws 23 in one direction the motor unit will beelevated and supported upon the trucks, and upon turning saidjack-screws in the reverse direction the motor unit will be lowered.

With the motor unit positioned over the pump head 3 and lowered into thetable plate 7, it will be secured in place by suitable bolts 14 of themotor stand 12 and engaging into scre -threaded orifices 26 in saidplate.

When it is desired to move the motor unit from over the pump head, themotor stand is first disconnected from the table plate 7 and thejack-screws 23 manipulated to elevate the motor unit and support it uponthe trucks. The entire motor unitmay then be drawn laterally along thetracks and away from over the pump head, suitable stops 27 beingassociated with the tracks to limit the travel of the trucks. To replacethe motor unit this operation is reversed, that is, the trucks carryingthe motor unit are moved to a position to bring the motor directly overthe pump head and the. jack-screws then manipulated to lower the motorunit upon the table plate 7 free from support by th trucks,

and the motor stand bolted to the table plate.

The trucks may then be removed until agaiin needed ormay be left inplace ifdesire Further, if desired the motor stand 12 may becut awayopposite the opening 15, as indicated in dotted lines in Fig. 2, so thatthe power unit may be moved in either direction to and from the pumphead.

It will be evident that with a power unit in which the supporting baseor stand has a side opening, the entire power unit may be movedlaterally from and to the pump head and over such parts as project abovethe pump head, without elevating the power unit more than just enough totransfer the weight of the power unit from the pump head to the trucks.

The mechanism above described provides a strong, durable and simplestructure capable of fulfilling all of the objects primarily stated, andwhile embodying a preferred form of structure it is only intended topresent one ofthe many forms of which the invention is susceptible,therefore, it is to be' understoodthat I do not wish to limit theinvention beyond the scope of the following claims.
